Bulldozers and hand crews will continue working through the night, but fire officials are now working to demobilize and start releasing resources, officials said Tuesday evening.

The smoke from the fire has diminished, but could continue to affect the area for days to come.

Fire officials are asking the public for help in determining the fire’s cause.

Cal Fire investigators now urge anyone in the area of Highway 128 between the Canyon Creek Resort and Pleasant Valley Road between the hours of 8 p.m. and 10 p.m. on July 4 to call the Cal Fire Arson Hotline at (800) 468-4408.

Those who have information or descriptions of people or vehicles that were in the area can remain anonymous, Cal Fire officials said.
